Different Types of Jackets for Stainless Steel Tanks

What Are The Different Types of Jackets for Stainless Steel Tanks?

Stainless steel tanks are widely used in various industries for storing and mixing liquids or materials. They have many advantages over other types of tanks, such as durability, corrosion resistance, easy cleaning, and high temperature and pressure resistance. However, sometimes these tanks need to be heated or cooled to maintain the desired temperature of the contents. This can be done by using a jacket, which is a layer of material that surrounds the tank and allows heating or cooling of the contents. A jacket can improve the temperature control and the heat transfer efficiency of the tank. In this article, we will explore different types of jacketed vessels, their applications, and the advantages they offer in maintaining optimal temperature conditions.

Different Types of Jackets for Stainless Steel Tanks

There are different types of jackets for stainless steel tanks, depending on the application and the heating or cooling medium. Here are some of them:

  • Conventional jacket: This type of jacket is best for small volume tanks under 300 gallons or high-pressure applications where the internal pressure is twice that of the jacket pressure. Conventional jackets utilize fluids like water and oil to facilitate heat transfer between the jacket and the container. These jackets create an annular space between the vessel walls, allowing the fluid to flow and regulate temperature. Although thicker and costlier than other types, conventional jackets have the advantage of achieving the lowest pressure drop. They are suitable for low-pressure operations and smaller containers.
  • Dimple jacket: This type of jacket is a cost-effective solution for handling internal vessel pressure. Dimple jackets are characterized by the presence of dimples or divots on their surfaces, which enhance turbulence within the jacket and improve heat transfer. These jackets are thinner and more affordable compared to conventional jackets while maintaining strength. Dimple jackets come in various sizes, shapes, and pressure ratings, making them versatile and suitable for larger containers. However, they are not recommended for extreme thermal cycling between very low and high temperatures. Dimple jackets are best used in applications that don’t require extreme temperature changes. They can use steam, water, oil, or other fluids as the heating or cooling medium.
  • Half pipe coil jacket: Half-pipe coil jackets consist of a coil welded to the vessel, positioned underneath the jacket. This configuration allows for regulating the fluid path to adjust the temperature of the entire vessel or specific sections. These jackets are moderately priced, ideal for high-pressure environments, and offer a rating of 750 psi. They are particularly suitable for liquid heat transfer and high-temperature applications.

These jacketed tanks are used in various industries including food processing, brewing and fermentation, cosmetics, cannabis extraction, chemical and pharmaceutical, etc. Choosing the right type of jacket for your stainless steel tank depends on several factors, such as the volume, shape, pressure, temperature, and contents of the tank. You also need to consider the cost, maintenance, and operation of the jacket over its lifespan.
